Alternative bicycle pavement marking studies using a bicycle simulator
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The past decade has seen increased public interest in sustainable transportation modes in the U.S. However, there is a relative lack of guidance regarding ... -
Artificial intelligence techniques for modeling dynamic traffic behavior at bottlenecks
(University of Missouri--Columbia, 2014) -
Automating traffic studies at modern roundabouts: a feasibility study
(University of Missouri--Columbia, 2007)The modern roundabout is growing in popularity as an alternative intersection design, however it presents engineers a new quandary. At a traditional intersection, traffic movements may more easily counted given vehicle ... -
Driving simulator use and calibration for work zone merge sign evaluation
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Work zones on highways have the potential to increase crash risk; therefore, efficient and noticeable signs play a critical role in enhancing highway ... -
E-scooter simulator development and applications
(University of Missouri--Columbia, 2021)Although electric scooters have brought a lot of convenience to people's lives, the laws and regulations related to it are just being developed, and the number of people injured by electric scooters is increasing every ... -
Empirical study of freeway interchange crash characteristics and influence areas
(University of Missouri--Columbia, 2016)Factors that affect drivers at interchanges are various and include changing lanes, changes in speed limits, and lengths of speed-change lanes. State Departments of Transportation (DOTs), local authorities, and transportation ... -
External communication displays for connected truck platoons in mixed traffic : a federated simulator study
(University of Missouri--Columbia, 2019)Truck platooning is anticipated to be the first widespread deployment of connected or automated vehicles (CAV). In addition to familiarizing the public with the function of CAV, a truck platoon has proven benefits to fuel ... -
Federated multimodal simulators in transportation
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As transportation involves a multiplicity of modes, there is a need to explore multimodal simulators in transportation and the integration of multimodal ... -
Implementing data-driven decisions for asset management in local communities
(University of Missouri--Columbia, 2016)The successful implementation of Transportation Asset management (TAM) by local governments facilitates the optimization of limited resources. The use of a data-driven TAM program helps to identify and prioritize needs, ... -
Investigation of smart work zone technologies using mixed simulator and field studies
(University of Missouri--Columbia, 2020)Safety is the top concern in transportation, especially in work zones, as work zones deviate from regular driving environment and driver behavior is very different. In order to protect workers and create a safer work zone ... -
Investigation of transportation innovations for food delivery and truck platoons
(University of Missouri--Columbia, 2022)Studies find that low-income areas are underserved by food retailers and have less access to healthy food, contributing to health disparities. A section of this thesis examines micromobility, drones, and ridesharing that ... -
Maintenance of traffic for innovative geometric design work zones and calibrating highway safety manual for Missouri interchanges
(University of Missouri--Columbia, 2016)As the nation's population continues to grow, the users of highway network face increased safety risks, delays and congestion. Budget constraints at many public agencies frequently make infeasible the construction of new ... -
Modeling pedestrian crash severity in St. Louis using random forests and mixed logit techniques
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] The pedestrian-vehicle crashes in the City of St. Louis is a major concern due to the high magnitude of injuries and fatalities compared to ... -
Operational analysis of cross-country trips on rail in Vietnam
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The analysis of current transit conditions is vital for planning and forecasting future transit demand. Previous analyses of Vietnam railways have ... -
Pattern recognition based microsimulation calibration and innovative traffic representations
(University of Missouri--Columbia, 2008)Even though calibration techniques for traffic simulation abound, this dissertation presents the first mathematical formalization using representations and invariants. The calibration is defined succinctly over three levels ... -
Red light running at traffic circles: estimation and evaluation of countermeasures effectiveness
(University of Missouri--Columbia, 2013)The complicated legacy design of traffic circles results in operational and safety deficiencies. This type of intersection design is commonly used at major roadways in Cochabamba, Bolivia. Traffic circles are intended to ... -
Safety evaluation of large truck-passenger vehicle interactions and synthesis of safety corridors
(University of Missouri--Columbia, 2007)Insights into the nature of large truck-passenger car interactions and the understanding of safety corridors can lead to improvements in the safety and efficiency of freeway operations. One main contribution of this thesis ... -
Safety evaluation of roundabouts at freeway ramp terminals and HSM calibration
(University of Missouri--Columbia, 2017)Although the conventional understanding is that roundabouts have the potential to improve safety at intersections, particularly by reducing more severe crash types, there is limited knowledge on their safety impacts when ... -
Safety modeling for two certain urban intersection types, HSM calibration, and crash severity distribution
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] According to several years' official crash data, a significant proportion of crashes happened at roadway intersections in Missouri. Of those intersection ... -
Simulator and field study of effectiveness of speed management methods in work zone in Missouri
(University of Missouri--Columbia, 2022)The objective of this research is to examine the effectiveness of six speed countermeasures in reducing vehicle speeds in work zones. Speed countermeasures such as law enforcement (active and passive), speed trailer ...
